Answer:
1. m= -2 1/3
2. m=35 (35 divided by -5 is -7 and -7+1 = -6)
3. m=-4 (2 times -4 is -8, 4+-8 equals -4)
Step-by-step explanation:
Answer:
event A is dependent on event B since roll 3 will result if you select a face card
Check the picture below.
in the picture below, the bottom part
notice, 69° + 21° = 90°, so 21° and 69° are really complementary angles, sharing the same quadrant, meaning for any two sides of lengths say, a,b one angle will have a tangent of say b/a, then the other will have a tangent of a/b.
namely the tangent of each angle, is simply the other's tangent upside-down.
Should be 105°.
The straight line equals 180°, and since you already have 75° you just subtract.
